dl2_009_Coin counter does not work

1．Does the credit on the screen increase?

If it increases,
check the wiring between the analog counter and I/O board.
The analog counter is the J9 2 pin-connector on the I/O board.

Picture: Location of the J9 connector If it does not increase, see "Credit does not increase."
